I've ridden 250 two-strokes for over twenty years now, and I've always ridden two-strokes for the entire thirty years that I've been riding, other than the occassional little spin on someone else's bike. I'm starting to want more and more to replace my trusty old pal, my KDX 250. I've ridden plenty of XRs, and didn't really care for them, too overweight and underpowered for my tastes (yes, I know about the XR 650, but it would be a handful in the tight, nasty woods that I ride in, and it's really over weight) and I just don't care for their lazy, grunty power. I've rode a YZ 400 F a few times, and the power is much better than an XR, but it just felt so, well, alien after all these years of two-strokes. My experience in four-strokes is limited, but I am getting curious about owning one. How many of you guys were long-term two-strokers, and how long did it take you to get the "feel" for the four-stroke power? The one thing that really throws me off when I ride a four-stroke is the engine braking, it just totaly throws my timing off.
